can someone please explain

Well, I got here too late and other people had already explained. So instead, I decided to play games with it, like getting it onto one line and getting rid of the well-named variables. (Honestly, naming a variable "count" when it's perfectly obvious that it's a counting variable... if you're not careful, people will be able to read your code...) So, um, this may not be helpful or answer your question, but it was fun:

print"$_ => $}{$_}\n"for grep{!$!{$_}++}map{$}{$_}++;$_}@Clec_id; 
$;=sub{$/};@;=map{my($a,$b)=($_,$;);$;=sub{$a.$b->()}}
split//,".rekcah lreP rehtona tsuJ";$\=$ ;->();print$/
